AUTOMATIC REFRIGERATING APPARATUS FOR USE IN CONNECTION WITH FERMENTINGOPERATIONS.

SPECIFICATION forming part of Letters Patent No. 768,7 72, dated A g 30,1904. Application filed May 29, 1903. Serial No. 159.387. (N0 model.)

To all whom, it may concern.-

Be it known that I, WALTER VON ROUGE- MONT, a subject of the GermanEmperor, residing at Rittergut Hohburg, near Wurzen, Saxony, Germany,have invented certain new and useful Improvements in AutomaticRefrigerating Apparatus for Use in Connection with FermentingOperations; and I do hereby declare the followingto be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in apparatus for automaticallycontrolling the supply of water to a pipe used for maintaining therequired temperature in a fermenting-vat such as is used indistilleries; and it consists in theconstruction, combination, andarrangement of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an elevation, partly insection, of a refrigerating or attemperating apparatus embodying myinvention; and Fig. 2- is a detail sectional view showing thewatersupplycontrolling valve and its connections.

The water-supply valve of the refrigerating or attemperating pipe 6',havingthe coil (1 in the vat a, is connected with a contact-thermometer6, arranged in the fermenting-vat a, by means of suitable actuatingparts as well as by an electric circuit (Z CZ, so that upon any undueincrease of temperature in the fermenting-vat the circuit (Z (Z isclosed by the column of mercury, and thereby the valve or is opened',thepipe 7* being thus put in action owing to the passage of watertherethrough from the cistern p. If in connection therewith thetemperature in the fermenting-vat decreases again to such an extent thatthe circuit (Z cl is interrupted by the falling of the column ofmercury, the valve or closes, thereby putting the attemperating-pipe outof action. If very considerable cooling is to be effected, it isadvisable so to connect the pipe 0' with the watensupply that the watershall flow through said pipe at the pressure prevailing in thewatersupply, as indicated in Fig. 1.

The valve is so constructed that it can be connected with a supply ofwater under pressure without its being necessary to employ a powerfulelectric current for opening the for raising the valve a, which is underpressure, from its seat, the rod 2; is 100 ely guided in the valve-cover10, so as to avoic friction, To effect a tight packing between the coverto and the rod or, a flexible casing 00 is fixed to the central portionof the cover, its lower end being connected with the rod 1; and thecasing 0 being put under tension by means of a spring f, arranged in theinterior thereof. The movable parts are balanced by the balance-leverK1, the pivot of which is indicated at 2".

By this construction, combination, and arrangement of devices thevalve-body, With the actuating parts belonging thereto, can be so easilymoved that the weak electric current is at all times sufi'icient foropening the passage for the flow of water through the pipe 9* and thecoil 11 in the fermenting-vat.

What I claim, and desire to secure by Letters Patent, is-

In apparatus of the class described, the combination of a cooling-vat, awater-coil therein, a water-supply element connected to the said coiland including a closed valve-box, a valve therein to control the supplyof water to the coil, a rod attached to said valve and operating in anopening in the valve-box, a flexible casing in the latter, aroundsaidopening and rod, and having one end attached to and movable with therod, a balance-lever attached to said rod, an armature attached to saidbalancelever, an electromagnet, and a circuit-closing thermometer in thevat, and in electrical connection with the windings of theelectromagnet, substantially as described.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
